HEATING APPARATUS.

Application filed October 5, 1925.

' mum of radiation with the minimum of casing in which the radiators are located.

It is a further object to provide a construction consisting of a plurality of detachable, interchangeable units whereby any number of units may be assembled in anydesired relationship depending upon the conditions of installation, thus varying units of standard manufacture to meet different conditions of installation. I

In the accompanying drawings: Figure 1 is a side elevation of the completely assembled unit with the side wall removed to disclose the interior of the unit. Figure 2 is an elevation from another side of the unit looking at the right hand of Figure 1.

Figure 3 is a plan view of the unit from the top. a

Figure 4 illustrates a method of alternative assembly of the interchangeable sections. Referring to the drawings in detail, 1- is a bottom section provided with an inlet opening 2. The bottom section is provided with up r and .lower flanges 3 for resting on the oor, and for supporting the upper sections on its margin. The top and bottom of the bottom section are both 0 en, the lower portion bein closed by the oor and the upper portion eing open for communication with the open bottom of the air tempering section 4, the side walls of which are provided with flanges 5 for resting on the adjacent sections for supporting an adjacent section. Within this tempering sectionis a radiator preferabl of the Aero Fin type designated 6 whic from the steam line 7.

of casing than would be the case if the radiator were disposed'horizontally. To one side of the radiator between it and one wall of the casing is a partition 8 located diagonally in the casing having an opening 9 in the partition, closed by a diagonally disposed damper 10 which may be actuated in any desired means as by an external handle 11. The upper end of this section carrying a tempering radiator and damper is open at the top so that the air which either passes over the radiator or is by-passed through the opening 9, may pass directly upwardly into the open-ended casing 12 known as the blower section. A

This blower section is provided with the flanges 13 and carries a plate either separate from or integral with the upper end of its body, such plate being designated 14. This plate suspends the blower which consists of a casing 15, a motor 16 and a roller or-fan 17. 18 designates the eye of the fan. This fan casing and fan mechanism is provided with angle irons at the top thereof at 19 adjacent the discharge opening .20, which angle irons rest upon cushions 21 upon the taming a diagonal baffle plate 25 having a Y damper opening 26 adapted to be closed by a damper 27 operated in any desired means as by an external handle 28.

It will be understood that this damper operating mechanism may be automatic, manual electrical or mechanical and may be inside or outside the casing.

The to of this heating section is open to permit 0 the vertical discharge of the air" which has been heated or by-passed through the damper opening 26.

The fan casing 15 is further supported by a bolt 29 resting on a cushion 30 carried by the plate 14 and connected at its other en to a bracket 31 on the fan casing.

Method of operation.

Assuming that the several sections have been stacked as in Figures 1 and2, the cold air is drawn in at the bottom of the stack through the o ening 2 and either passes upwardly entirely over the radiator 6 to be tempered or partially through the opening 9 where it is by-passed entering the eye of the blower 18 and is discharged upwardly through the opening 20. As there is no other means of communication between the blower section and the heater section, the air thus discharged having been tempered it is passed over the heating radiator or bypassed around-the heating radiator partially and discharged upwardly into the room. It will be realized that suitable devices are provided for controlling these radiators in the usual fashion so that one or both may be in operation or both may be cut off.

It will be understood that these sections maybe arranged as desired in any combination or number and with space or sections between them to increase the size of the stack, the air capacity and the like. V

It will be understood that I do not desire to be confined to the details of my invention but desire to comprehend Within it such modifications as may be necessary in the adaptation of it to varying conditions of installation and use.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a heating apparatus, a casing having means for the introduction of air at the bottom thereof and the exit of air at the top thereof, -a tempering radiator in the bottom thereof, a blower for drawing the air over the tempering radiator and discharging it into another portion of the casing, and a heating radiator in said portion of said casing, partitions adjacent each of said radia-v tors having openings therein, dampers adapted to regulate the passage of air through said openings whereby air may be by-passed around said radiators.

2. In a heating apparatus, a casing having exit and entrance openings for air, a radiator therein, a partition between said radiator at one end and a wall of the casing separating that portion of the easing into two compartments, said wall having an opening and a damper to control said opening for controlling the by-passing of air around said radiator, said radiator and said partition being diagonally disposed within said casing.

3. In a heating apparatus, an inlet section having an inlet and discharge opening, a tempering section having a tempering radiator and by-pass means, a blower section having a blower and a heating section having a heating radiator and a bypass means,

said sections being detachably mounted one on the other in the desired order for tempering, heating and by-passing air.

4. In a heating apparatus, an inlet section having an inlet and discharge opening, a tempering section having a tempering radiator and by-pass means, a blower section having a blower and a heating section having a heating radiator and a by-pass means, said sections mounted one on the other in the desired order for tempering, heating and bypassing air.

5. In a heating apparatus, a main casing divided into a plurality of compartments having means to permit the passage of air from one compartment to the other, a radiator in one of said compartments through which air is adapted to pass, a partition to one side of said radiator between the wall of the main casing and the radiator, and a damper in said partition for controlling the opening through the partition to by-pass air around the radiator.

6. In a heating apparatus, a main casing divided into a plurality of compartments having means to permit the passage of air from one compartment to the other, a radiator in one of said compartments through which air is adapted to pass, a partition to one side of said radiator between the wall of the main casing and the radiator, and a damper in said partition for controlling the opening through the partition to by-pass air around the radiator, said radiator and said partition both being diagonally arranged together with the diagonally supported damper.

In testimony whereof. I aflix my signature.
